Application filed September 6, 1916. Serial No. 118,675.

Among the main objects of the present in-. ventlon one is to provide eflicient actuating connections intermediate the space key and dog rocker which enable the dog rocker to be actuated independently of said connections and the space key when the dog rocker is actuated by the universal bar; and another is to provide means whereby such connections may be readily adjusted to accord with the adjustment for pull of the dog rocker by the universal bar.

To the above and other ends which will hereinafter appear, my invention consists in the construction, arrangements and combinations of parts set forth in the following description and particularly pointed out in the appended claims.

I have shown my invention embodied in the present instance in a machine involving escapement mechanism devised in-part by George A. Seib and forming the subject-matterof an application filed by him of even date herewith and bearing Serial No. 118,607.

My invention lsdirected more particularly to the connections intermediate'the space key and dog locker and while particularly adapted for use in a construction such as that dis closed in said Seib application, such connections may be used with equal efliciency in combination with different forms of escape ment and controlling'means therefor.

The frame of the machine comprises a base 1, and top plate 2 supported from the base by corner posts, not shown. A. suitable power driven carriage (not shown) is mount-v ed above the top plate for movement from.

side to side of the machine and carries a platen 3 and a feed rack 4, The feed rack meshes with an escapement pinion 5 operatively connected with an escapement wheel 6. For the purpose of my present invention it is immaterial what character of escape as a whole by the reference numeral 9. This dog rocker is pivoted at 9 to a suitable bracket plate secured to the top plate of the machine and is constructed in a manner to be hereinafter more clearly ointed out.

Upwardly and rearward y striking type bars 10 are mounted on a pivot wire 11 carried by a type bar segment '12. The heel of each type bar is received in a guide slot 13 and is provided with a cam or contact edge 14 which coii'perates with the forward edge of a universal bar 15. The ty e bars may be actuated from the printing eys by any suitable actuating devices, and in a.

movement of a type bar to the printing position the universal bar is engaged by the contact portion 14: and moved rearwardly to actuate the dog rocker through suitable in- The segmental universal bar 15, which is arranged for cooperation with the heel of each type bar, is provided with a centrally disposed upwardly extending lug or finger 16 to'which is fixed a forwardly projecting guide pin 17 received in a guide opening in the body portion of the type bar segment 12. Each side portion of the universal bar has a rearwardly projecting arm 18 which is pivoted at its rear end, as at 19, to an upwardly projecting crank arm 20 which extends from a rock shaft 21.v This rock shaft extends transversely of the machine and is supported at its ends by pivot screws (not shown) threaded into depending bracket arms 22 which project from the top plate of the ma chine. The rock shaft is also provided with a centrally disposed upstanding crank arm or actuating member 23 provided at its upper end with a laterally extending headed pin 24. This pin is received in a slot 25 of an actuating member or link designated as a whole by the reference numeral 26. Said link or member 26 is also provided with a depending arm 27 provided at its lower end witha bentend which constitutes an engaging portion or contact 28 which normally bears against the rocker arm 23. A contractile spr1ng29 is connected at the rear end to one of the crank arms 2023 and is secured at its forwardend to a suitably fixedportion of the machine. The force of this spring is. exerted to return .the rock shaft and the universal bar connected therewith to normal position. The link 26 is apertured at its rear end to receive a headed pivot pin 30 which projects from one side of a depending arm 31 on the dog rocker, thus pivotally connectin the link 26 to the dog rocker. The depen ing arm 31 of the dog rocker is provided with an openin 32 through which the stem of a headedad usting screw 33 passes freely, the threaded end of the screw being received in a tapped opening in the body portion of the dog rocker. A coiled expansion spring 34 (see Fig. 3) surrounds the stem of. this screw and is received at its-forward end in a de pression 35 in the body of the dog rocker, the opposite end of said spring bearing against the arm 31 and pressing it against the head of the screw 33. The upper end of the arm 31 is apertured to receive a headed screw 36 taking at its threaded end in a tapped opening in the body of the dog rocker. The construction is such that when the screw is loosened the arm 31 may receive a pivotal adjustment around the screw 36 asa center. When, however, this screw 36 is tightened it effects a clamping of the arm 31 between the head of the screw and the'body of the dog rocker in order-to secure the arm in its adjusted position. It will be understood that when the screw 36 is loose a forward adjustment of the screw 33 will cause the head thereof to bear on the arm 31 and force the lower end of the adjustment of the arm 31 is to provide for" the proper pull or operation of the dog maker and escapement through an actuation of the universal bar. It will be understood that the first portion of each printing stroke of a type bar is efiected independently of the universal bar and the parts controlled thereby, and that after the universal bar is taken up by the type bar an actuation of the link 26 and the dog rocker controlled thereby is first efi'ected through the engagement of the contact 28 with the actuating arm 23. It will be observed that the distance from the pivotal center'of the rock shaft 21 to the contact 28 in the resent instance is less than one-third the distance from said ivotal center to the pin 24. After a slight and relatively slow movement of the dog rocker has been effected through the engagement of the arm 23 with the contact 28, the pin 24 will reach the end of the slot 25, thus engaging the link at this point and continuing the movement of the link and dog rocker through the connection thus efl'ecte'd.

Thedog rocker and the specific means for controlling the same from the universal bar ,herein disclosed are not of my invention but are the invention of George A. Seib and are claimed in the. application hereinbefore referred to. This mechanism is 'shownand 'described in the present instance inorder to arrive at a clearer understanding of the feature of my invention comprising the means whereby the dog rocker may be actuated b the space key and afford an actuation o the dog rockerby the universal bar independently of said means, and likewise enable an adjustment of the connections from the space key to the dog rocker to be efiected to accord with the adjustment of the connections intermediate the universal Ibar'and dog rocker.

Referring more particularly to Figs. 4 and 5, it will be seen that a space key or bar 3'? is connected with the horizontally disposed parallel space key levers 38 fulcrumed at their rear ends, as at 39, to brackets 40 which are secured to the base of the machine. These space key levers are rigidly connected by a cross bar 41 apertured at. 42 about midway in'the length thereof for the free passage therethrough of an actuating link 43. The lower end of this link is threaded at 44 and extends beneath the cross rod or bar 41 where it cocperates with 'a nut 45 nicked at 46 for cooperation with a stgaddle screw driver. The upper side of this nut is cupped o1 recessed to receive a pad 47 of leather or like material which is adapted to contact with the underside of the cross bar 41. This pad is threaded-t0 receive the threaded end of'the actuating link 43, so

that as the nut is turned a correspondingturning movement of the pad is effected. A returning spring 48 is connected at one end with a space key lever and at its opposite end to a suitable support in order to efl'ect a return ofthe space key to normal position. The upper end of, the actuating link 43 is provided with ahook 50 adapted to be received in any one of the three openings 51 in a substantially disposed two-part actuatingmember or lever, indicated as a wholeby the reference'numeral 52. The hook may be retained against accidental displacement A contractile returning spring 57 is connect- 'ed at one end to the bracket and at its opppsite end to the two-part actuatingmemr 52. This member comprises a plate-like part 58 which is pivoted to the bracket, and a second part 59 slotted at 60 to receive the stems of headed screws 61 which are received at their threaded ends in tapped openings in the part 58. By this construction the member 59 may receive a fore and aft adjustment on the member 58 and be secured in its adjusted position by tightening the screws 61, thus clamping the member 59 be tweenthe heads of said screws and the member 58. the lever-like actuating member 52 may thus be effected in order to bring about an adjustment of the actuating endof said member for purposes which will hereinafter ap-- pear. The part 59 is provided with an inclined edge or cam 62 which cobperates with a headed pin 63 projecting from the opposite side of the dependingarm 31 of the dog rocker from that on which the pin '30 is mounted. A reanwardly projecting fin er 64 extends from the part 59 and is provi ed with an upper contact edge or face 65 which terminates at its forward end at the cam 62. It will be understood that after the arm 31 receives the required adjustment fore or aft of the machine relatively to. the dog'rocker, the member 59 may receive a corresponding adjustment so as to maintain proper coiiperative relation between the cam .62 and the pin 63 andalways actuate the dog rocker in a uniform manner from the space key, irrespective. of the position to which the arm 31 may be adjusted.

During the movement of thewiog rocker eflected by an actuation of the universal bar, the pin 63 will ride freely along the A lengthening and shortening of relieve the touch on the space key of this face 65 of the member 52- without disturbing said member or the link 43, and space key 37, these parts remaining quiescent at this time. o It will be understood, therefore, that an operation of the dog rocker by the printing keys is effected through the universal bar and its connections independently of the space key and the separate and distinct intermediate connections between the space key and the do rocker. On the other hand, an actuationjo? the space key is eflective to pull down the member-52 around its pivot 54, and cause the cam 62 to actuate the do rocker independently of the universal bar. Thus at this time the link 26 moves with the dog rocker but by reason of the pin' and slot connection 24-25 between said link and the arm '23, said arm, the rock shaft 21 and the universal bar will remain at rest so that the dog rocker may be actuated by the space key independently of the universal bar and certain parts of the train of actuating connections by which the dog rocker is operated from'the universal bar. 1

Itwill be seen from the foregoing that an actuation of the dog rocker from the universal bar may be effected at the last portion of the printing movement of the type bar without the necessity of operating the independent train of connections between the space key and do rocker, thus relieving the touchof the ad itional weight and resistance that these parts-would present if actuated at this time. On the other hand, the actuation of the dog rocker by the space key is efiected independently of the universal barand the princi al connections between said barand the 0g rocker so as to additional weight and resistance.

For the purpose of my present invention any suitable connection between the universal bar and the dog rocker may be employed, but preferably connections of such. a character as to enable the dog rocker to be actuated independently of the universal bar and its connections or some of them.

It is apparent that the finger 64 serves as a stop or guide to prevent the spring 57. from pulling the two-part lever 52 up out of cofiperative relation with the pin 63, both when the parts are in normal position and also when the pin 63 is moved rearwardly by the universal bar independently of the two-part lever, the finger 64 at all times bearing against the underside of the pin 63.

The term dog rocker is employed herein in a generic sense and is intended to cover a dog carrier or holder however constructed L2 or actuated.
